📊 Math
Q. Which formula gives the simple interest (SI) on a principal P at rate R% for T years?
  • (A) SI = P + R + T
  • (B) SI = (P × R) + T
  • (C) SI = (P × R × T) / 100
  • (D) SI = P × (1 + R/100)^T
💬 Discuss
✅ Correct Answer: (C) SI = (P × R × T) / 100

Explanation: Correct: SI = (P × R × T) / 100 is the standard simple interest formula. Option1 and Option2 are dimensionally wrong. Option4 is the compound interest formula, not simple interest.

📊 Math
Q. What is the simple interest on Rs. 1000 at 5% per annum for 2 years?
  • (A) Rs. 50
  • (B) Rs. 100
  • (C) Rs. 200
  • (D) Rs. 150
💬 Discuss
✅ Correct Answer: (B) Rs. 100

Explanation: SI = (1000×5×2)/100 = (1000×10)/100 = 1000×0.1 = 100. Option1 (50) is for 1 year at 5%. Option3 & Option4 are too large.

📊 Math
Q. If principal is Rs. 1500, rate 4% per annum for 3 years, what is the total amount (principal + SI)?
  • (A) Rs. 1680
  • (B) Rs. 1620
  • (C) Rs. 1560
  • (D) Rs. 1740
💬 Discuss
✅ Correct Answer: (A) Rs. 1680

Explanation: SI = (1500×4×3)/100 = (1500×12)/100 = 180. Amount = 1500+180 = 1680. Option2 (1620) would be SI=120; Option3 (1560) SI=60; Option4 incorrect.

📊 Math
Q. Simple interest is Rs. 240 for 2 years at 6% per annum. What was the principal?
  • (A) Rs. 2000
  • (B) Rs. 1500
  • (C) Rs. 1200
  • (D) Rs. 1000
💬 Discuss
✅ Correct Answer: (A) Rs. 2000

Explanation: P = SI×100/(R×T) = 240×100/(6×2) = 24000/12 = 2000. Other options give wrong division results.

📊 Math
Q. If simple interest earned on Rs. 800 for 3 years is Rs. 120, what is the annual rate?
  • (A) 4%
  • (B) 5%
  • (C) 6%
  • (D) 7.5%
💬 Discuss
✅ Correct Answer: (B) 5%

Explanation: R = SI×100/(P×T) = 120×100/(800×3) = 12000/2400 = 5%. Option1 gives too small SI, Option3 & Option4 too large.

📊 Math
Q. A sum of Rs. 5000 yields Rs. 750 as simple interest in a certain number of years at 5% p.a. What is that time?
  • (A) 2 years
  • (B) 3 years
  • (C) 4 years
  • (D) 5 years
💬 Discuss
✅ Correct Answer: (B) 3 years

Explanation: T = SI×100/(P×R) = 750×100/(5000×5) = 75000/25000 = 3 years. Other options don't match the division result.

📊 Math
Q. At what simple interest rate will a principal double in 10 years?
  • (A) 5%
  • (B) 8%
  • (C) 10%
  • (D) 12%
💬 Discuss
✅ Correct Answer: (C) 10%

Explanation: Doubling means SI = P. So P = P×R×T/100 ⇒ 1 = R×10/100 ⇒ R = 100/10 = 10%. Other rates give different multiples of P.

📊 Math
Q. What is the simple interest on Rs. 2000 for 6 months at 8% per annum?
  • (A) Rs. 80
  • (B) Rs. 160
  • (C) Rs. 40
  • (D) Rs. 100
💬 Discuss
✅ Correct Answer: (A) Rs. 80

Explanation: T = 6 months = 0.5 year. SI = (2000×8×0.5)/100 = (2000×4)/100 = 80. Option2 would be for 1 year at 8% (160). Option3 & Option4 are incorrect.

📊 Math
Q. Which statement is true?
  • (A) Simple interest depends on principal, rate and time; interest each year is same.
  • (B) Under simple interest, interest is added to principal each year.
  • (C) Simple interest and compound interest are identical for multi-year periods.
  • (D) Simple interest rate changes every year automatically.
💬 Discuss
✅ Correct Answer: (A) Simple interest depends on principal, rate and time; interest each year is same.

Explanation: Correct: SI = PRT/100 so depends on P,R,T and yearly interest is constant. Option2 describes compound interest. Option3 is false unless rate=0 or time=1. Option4 is false.

📊 Math
Q. Simple interest on P for 3 years is equal to simple interest on Q for 2 years at the same rate. What is P:Q?
  • (A) 3:2
  • (B) 2:3
  • (C) 1:1
  • (D) 3:1
💬 Discuss
✅ Correct Answer: (B) 2:3

Explanation: SI ∝ P×T at same rate. If P×3 = Q×2 then P/Q = 2/3. Option1 is inverse. Option3 and Option4 don't satisfy the equation.
